Hear it in context
Notice where the phrase sounds natural.
You cooked, so I'll do the washing-up.
A: Can you give me a hand in the kitchen?
B: Sure, I'll do the washing-up.
Fix the pattern
One small grammar move makes it sound right.
Not: I'll do the washing-up of the dishes.
Say: I'll do the washing-up.
'The washing-up' already means the dishes — don't add 'of the dishes'.
